We have been having problems with our line for over a month now this is my second complaint, I have been logging problems with Webafrica and every time the log it and the the ticket gets closed, ticket number ***, we again got a call that the line is sorted but when I do a speed test it ie either low 20mb/s or high 20mb/s we are currently paying for a 40/10 line but not once has it been close to that, and yes all devices was disconnected when i did the test, this can not go on like this, i am paying for a service that i am not getting. Please have this sorted and I would like a refund, cause clearly I am not getting what I suppose to be getting.
